In my first post on removing duplicate PATH entries I used an AWK one-liner. In the second post I used a Perl one-liner, or more accurately, I tried to dissect a Perl one-liner provided by reader Shaun. Shaun had asked that if I was willing to use AWK (not Bash), why not use Perl? It occurred to me that one might also ask: why not just use Bash? So, one more time into the void.
